To ,ZZ whom, t may concern:

Be it known that I, ALBERT C. LUYCKX, a citizen of theUnited States of America, residing at Detroit, in the county of lVayne and State of Michigan, have invented certain new and useful Improvements in Barrel-Machines, of which t-he following is a specification, reference being had therein to the accompanying drawings.

This invention relates to that class of barrelmachine designed for forming barrel-bodies from wood veneer; and my invention consists in the improved construction, arrangement, and operation of an expansible forming-cylinder and in the means for compressing the veneer in the act of forming the barrel-body, all as more fullyhereinafter described,and sh own in the accompanying drawings, in which- Figure l is a vertical central longitudinal section through the machine. Figs. 2 and 3 are the two end elevations thereof, respectively. Fig. iisaside elevation thereof. i Fig. 5 is a cross-section on line 5 5, Fig. l. Fig. 6 is a detail perspective view of the sliding connection between the segments and the supporting-arms thereof, and Fig. 7 is a perspective view of the clamping-strip.

A is the shaft upon which the expansible forming-cylinder is mounted.

B is the supporting-frame, with vertical standards C C', provided with bearings D D for the shaft.

The standard C is formed with a hinge-joint at E and terminates at its upper end in a halfbearing D, adapted to support the trunnion a, formed at the end of the shaft, all so arranged that t-he upper section of the standard C can be moved out of the way to permit the removal of the barrel from the cylinder after it is formed.

The forming-cylinder is composed of segments F, the drawings showing four such segments, which collectively form a metal cylinder, with peripheral groovesb b near the ends, made of a size to receive the inner hoops for the barrel-body, the depth of the grooves being the thickness of the hoops. This forming-cylinder is made expansible in the following manner: Each segment is formed with a pair of radial arms c, terminating at their inner ends in bearings c', havinginclined undercut mortises which slidingly engage with correspondingly-inclined tenons d. The tenons at each end of the cylinder are carried by spider-cones G G, which are sleeved upon thc shaft and connected together by the tube H, whereby both move together.

The shaft A has at one end a screw-threaded portion e, which carries a nut f, provided with a hand-wheel I for turning it. This nut at its inner end abuts against the hub of the adjacent spider-cone and has an annular iiange h, by means of which the nut is held in contact with the spider-cone through the couplingsleeve j, screwed upon the hub of the spidercone, all so arranged that the nut is free to turn independently of the spider-cone, but carrying the cone with it. As both cones must move together, it will be seen by turning the hand-wheel the cones can be moved along the shaft in either direction, and as these cones carry the inclined tenons the latter will impart to the segments a radial expanding or coutracting movement. The segments are held against lateral displacement and radially' guided in their movement by a spider J, secured-upon the shaftA and having bifurcated arms, into which the radial guide-lugs t' on the inner side ofthe segments engage and in which they are guided by pins k, engaging into radial slots Z in the ends of theAspider-arms.

The rear side of the frame has two upwardly-projectin g supports K, in which is secured a transverse bar L, which forms the fulcrum for the power lever M, which is forked at its upper end and fulcrumed upon the bar L by means of bearings L in the forked ends of the lever. The long arm of this lever projects vertically downwardly below the fulcruln and thence forwardly, terminating in a footpiece m in convenient position for the operator to place his foot upon for actuating the lever.

The short arm of the lever M extends upwardly above the fulcrumv and terminates above the center of the forming-cylinder, and to the bifurcated ends of this short arm is fixedly secured the compressor-bar N, all so arranged that the operator by stepping upon the footpiece m of the lever will press the bar N against the face of the forming-cylinder. In this position the lever M may be locked by engaging it with one of the rackteeth n, formed in a guide-loop O, through which the lever M passes, a suitable spring n being provided to normally hold the presserbar out of contact with the drum. The long arm of the lever is formed rigid; but the ends forming the short arm are made of spring metal, so as to be slightly yielding when thc compressing-bar is forced down upon the forming-cylinder. The compressing-bar is made rounding upon its lower side, where it presses upon the forming-cylinder.

For revolving the forming-cylinder a gear'- wheel P is fastened upon the end of the shaft near the fixed bearing D', and intermeshing therewith is a pinion R, supported upon the frame in handy proximity to the operator in front of the machine and adapted to be revolved by a crank-handle, all so arranged that one complete turn of the handle will revvolve the forming-cylinder the exact distance apart at which it is desired to nail the outer hoops to the barrel-body.

My machine is designed for making barrels from Veneer and is operated in the following manner: To begin with, the forming-Cylinder is rst contracted. Then two complete hoops are slipped upon the cylinder into the annular grooves b, after which the forming-cylinder'is again expanded till the hoops are so tightly bound in the grooves that they are compelled to revolve with the cylinder during the formation of the barrel. The barrel is formed by inserting the edge of a sheet of veneer of suitable width under the compression-bar, clamping the same down tight upon the former, and revolving the barrel intermittently by turning the crank one turn at a time, while a second operator standing on the rear side keeps nailing on the Veneer to the inner hoops. New sheets of veneer are added as needed to complete the barrel, and the outer hoops are secured around in the same way, all in the well-known manner and forming no part of this invention.

As the forming-cylinder is of metal, it is obvious that the nails will become clenched upon the inside, and after the barrel is thus formed the forming-cylinder is collapsed and the barrel' removed. s

The advantage of my construction is that I can make perfect single or double ply veneer barrels from absolutely dry and seasoned veneer, as the compression-bar which does not roll, as in the other machines) being at the end of a power-lever presses the veneer so tightly that it is forcibly stretched and all wrinkles or inequalities are straightened out, while at the same time the forming-cylinder is uniformly and evenly expanded by the action of a screw to the limit of the hoops without danger of bursting the same or allowing the forming-cylinder to contract during the operation, so that the hoops are firmly held in the grooves and cannot slip.

In Fig. 7 I have shown a clamping-strip P, formed with a hook o at one end, an apertured ear o at the other end adapted to t over the drum and hold the end of the veneer or hoops against the face of the drum in making a barrel, a suitable wedge o` being inserted in the apertured ear to hold the clamping-bar down, or I may, if desired, dispense with the clamping-bar entirely and use a series of cams or other convenient means to accomplish this purpose. The clamping-bar is preferably slightlyT inwardly curved, so as to have a uniform clamping effect across the face ofthe drum.

What I claim as my invention is- 1. In an expansible forming-cylinder,com posed of a plurality of segments, the combination of a shaft journaled in bearings free to revolve and provided at one end with a screw-thread, a nut upon said screw-threaded portion of the shaft, a pair'of connected cones sleeved upon said shaft and adapted to be actuated by said nut to slide longitudinally of the shaft, a pair of radial arms on each segment projecting with their inner ends toward the faces of the cones respectively, a sliding connection between the inner ends of said arms and the faces of the cones adapted to expand and contract the segments by the sliding movement of the cones and means for radially guiding the segment-s in relation to the shaft.

2. In an expansible forming-cylinder, composed of a plurality of segments, the combination of the shaft A journaled in bearings and provided at one end with the screwthreads e, the nut f upon said screw-threads having the hand-wheel I, the cone-spiders G G sleeved upon the shaft and connected to move together, the coupling-sleevej uniting the screw-nut with the hub of one of the cones, free to revolve the nut independently of the cones, the tenons d formed on the cones, the radial arms c of the segments provided with bearings c having undercut mortises engaging with the tenons on the cones, the spider J fixed upon the shaft and having bifurcated arms, and the radial arms t' of the segments guided in said bifurcations.

3. In a barrel-machine, the combination with the frame and forming-cylinder supported in said frame free to revolve, the combination of the power-lever M fulcrumed in rear of the forming-cylinder and having a rigid long arm extending in rear and beneath the frame and forming a foot-lever, a guideloop O through which said foot-lever passes and having ratchet-teeth for engaging said lever, a flexible short arm bifurcated and extending upwardly over the rear of the forming-cylinder, and a compression-bar rigidly secured to the bifurcated ends of the short arm and extending longitudinally over the top of the forming-cylinder.

In testimony whereof I ailx my signature in presence of two witnesses.
